Last year, Costa Rica spent a whopping 299 days using renewable energy alone. In 2016, they have gone 150 days without burning fossil fuels.
Part of the reason for their success is that much less energy is used in Costa Rica than for instance, the United States, as the population of the Central American is just 4.9 million people.
According to a report from the Economic Commission for Latin America and the Caribbean, Costa Rica used 10,713 gigawatt-hours of electricity in 2015, 373 times less than the roughly 4 million gigawatt-hours used in the US.
Later this month, the Costa Rican Electricity Institute will unveil a massive new hydroelectric project six years in the making, called Reventazón.
"Revantazón is the largest public infrastructure project in Central America, after the Panama Canal," Mashable reported. "The dam's five turbines will have a generating capacity of 305.5 megawatts — enough to power around 525,000 homes."
